JAMES M. MCCOOL, OF MONTGOMERY, ALABAMA.

REFRIGERATOR;

SPECIFICATION formin part of Letters Patent No. 724,319, dated March 31,1903.

Application. filed July 29, 1902. Serial 110.117.488; (No model.)

To all whom it may concern.-

Be it'known that I, JAMES M. MCCOOL, a citizen of the United States,residing at Montgomery, in the county of Montgomery and State ofAlabama, have invented new and useful Improvements in Refrigerators, ofwhich the following is a specification.

This invention relates to refrigerators of that class embodying a seriesof independent storage-receptacles adapted to separately contain as manydifferent commodities orarticles.

The purpose, mainly, of the present improved form of refrigerator is toutilize cold currents of air in the most advantageous manner andestablish a circulation thereof around and between a series ofindependent receptacles or storage-compartments, which are accessiblewithout permitting the exterior warm air to flow into thecooling-chamber of the refrigerator and moderate the temperature of thelatter, and thereby economize in the use of ice in maintaining thedesired low degree of temperature.

A further purpose of the invention is to so construct a refrigeratorthat the cold-air currents will separate from and be uncontaminated bythe water of condensation or drip descending through the cooling-chamberfrom the ice-box, and thereby establish a dry cold, with materialadvantage in refrigeration.

A further aim of the invention is to provide a refrigerator having achamber in which are disposed a series of independent receptacles whichare accessible from the exterior without permittingthe entrance of thesurrou nding air to the said chamber, and also a cold-storage chamber atone end, which can be used without in the least aflecting theindependent reoeptacles, the said cold-storage chamber being arrangednear the ice or other refrigerant inclosure.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a perspective View of a refrigeratorembodying thefeatures of the invention. Fig. 2 is a longitudinalvertical section of the same, taken through the center thereof. Fig. 3is a transverse vertical section on the line 3 3, Fig. 2. Fig. 4 is ahorizontal section on the line 4 4, Fig. 2.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates an elongated rectangular inclosure or casing,which provides a refrigerating-chamber 2, and rising from the front endthereof is a vertical auxiliary inclosure or casing 3, having aninlet-door 4 and surrounding a cold-storage chamber 5. The bottom,sides, and end of the inclosure or casing 1, as Well as the similarparts of the inclosure or casing 3, and also the top of the latter, areformed with double walls which are spaced apart and have a suitableheatnon-conducting material, as clearly shown by Figs. 2, 3, and 4. Thedoor 4 will also be suitably packed in the most approved manner, and allof the well-known incidental structural features of refrigerators as nowcommonly manufactured and tending to produce a superior refrigeratinginclosure will be applied to the present improved device. Within theupper portion of the storagechamber 5 is an ice-chamber 6, having anopen bottom with an ice-rack 7 disposed thereon and also provided with adoor 8, which will be suitably packed to prevent the ice from beingattacked or afiected by the exteriorair when the door 7 is open. The topwall 9 of the ice-chamber is independent of the top wall of theinclosure or casing 3 for economic preservation of the ice in thechamber 6, and closely joined to the lower open end of the ice-chamberis a metallic chute 10, formed with a lower elbow 11 and an outletmouth12, extending into the chamber 2 at the front'of the latter.

Within the chamber 2 are a series of independent receptacles 13, whichare fully closed except at their upper ends and have blocks 14interposed between the bottoms thereof and the bottom of the chamber'2,the said blocks'being located at the corners of the bottoms of thereceptacles. By elevating or raising the bottoms of the receptacles 13airpassages are provided thereunder; Over the 1 top of the chamber 2 isa frame 15, compriscles 13 and hold the latter regularly spaced apart toform air-passages.

From the foregoing it will be seen that all the sides and bottoms of thereceptacles 13 are fully exposed to the influence of the cold air withinthe chamber 2. The independent receptacles 13 will be preferablyporcelainlined, and over their upper open tops transverse slides 19 aremounted to engage the grooves 17 and have central upstanding grips 20for operating the same and drawing them outwardly from either side ofthe casing or inclosure 1 to disclose andrender accessible either one ofthe receptacles 13 with which each codperates. The slides 19 havetransparent panels 21 therein, through which the commodities or articlescontained within the several receptacles may be inspected withoutopening the said slides.

The chamber 2 is separated from the lower portion of the chamber 5 by afront vertical partition 22, and therethrough the mouth 12 of the chuteextends and is disposed over the front end of a central trough 23,extending longitudinally through the chamber 2 and has adownwardly-directed curved outlet 24, projecting through the lowerportion of the rear end of the inclosure or casing 1, as clearly shownby Fig. 2. This trough 23 is disposed close to the bottom of the chamber2 and is gradually inclined downwardly from its front end to the outlet24. The water of condensation or drippings from the ice in theice-chamber fall downwardly through the chute 10 and strike the elbow 11and by the latter are directed into the trough 23 and pass out throughthe outlet 24.

The cold air passes from the ice-chamber 6 downwardly through the chute10 into the chamber 2 and circulates around the recep: tacles 13, andthere being no outlet or escape for the currents of air within thechamber 2, except through the door 8 when the latter is opened at longintervals to replenish the chamber 6 with ice, will result inmaintaining a uniform and low degree of temperature in the said chamber2.

The cold-storage chamber 5 can also be employed with advantage forpreserving meats or other large articles which are rendered readilyaccessible through the medium of the door 4 Without interfering with thetemperature of the chamber 2.

The improved refrigerator will be found exceptionally useful in stores,hotels, and other places where large quantities of different commoditiesare required to be refrigerated, and the proportions of the refrigeratormay be varied to accommodate different uses or to increase the capacitythereof. It will be also understood that the proportions and dimensionsof the improved refrigerator maybe varied to adapt it for domestic use,and in the construction of the device changes in the form and increasein the number of receptacles and a variation in the minor details may bemade without departing from the principle of the invention.

Having thus fully described the invention, what is claimed as new is 1.A refrigerator, comprising a front vertically-disposed cold-storagechamber, an icechamber located in the upper rear portion of saidstorage-chamber, the said ice-chamber being a closure distinct from thestoragechamber and having an independent door and also provided with adepending chute with a lower curvedend, a distinct refrigeratingchamberextending from the lower rear side of the storage-chamber and separatedfrom the latter by a partition through which the lower curved end of thechute extends, the bottom of the ice-chamber opening fully into theupper end of the chute, and a series of independent receptacles mountedin the refrigerating-chamber and having fully-closed bottoms and sidesand accessible from the top, the said receptacles being separated fromeach other and the adjacent sides and ends of the refrigerating-chamberand also having their bottoms elevated above the bottom of the latter.

2. A refrigerator, comprising a front vertically-disposed cold-storagechamber, an ice chamber in the upper rear portion of saidstorage-chamber in the form of a distinct in closure having adoor andalso provided with a depending chute with a lower rearwardlyprojectedend, a refrigerating-chamber connected to the lower rear portion of thestorage-chamber and completely separated from the latter by a partition,the lower end of the chute extending through the said partition abovethe bottom of the refrigerating-chamber, a series of independentreceptacles mounted in the refrigerating-chamber and having fully-closedbottoms and sides and accessible from the top, the said receptaclesbeing separated from each other and the adjacent sides and ends of therefrigeratingchamber and also having their bottoms elevated above thebottom of the latter, and a downwardly and rearwardly inclined troughextending from the partition under the lower end of the chute to andthrough the rear end of the refrigerating-chamber;

In testimony whereof I affix my signature in presence of two witnesses.
